Title: Improvements in secret service systems for rural and party line telephones
IPC: H04M1/70
Filed: 1924-09-02
Abstract: 243,791. Sherman, H. B. Sept. 2, 1924. Party-line exchange systems ; automatic exchange systems.-When a subscriber on a partyline, C. D lifts his receiver 19 to initiate or answer a call, a relay 1 is energized over its high and low resistance windings 2, 3 in series with a relay 5 at the exchange and removes a short-circuit from the receiver, at the same time shortcircuiting its high-resistance winding 2 to prevent the energization of the corresponding relay of any other subscriber on the line, so that secrecy is ensured. Operation of the relays 1, 5 and of the substation bell Band magnets F and exchange indicator 31, 30 takes place over the two party-line wires in parallel. In the case of a call for another subscriber on the same line, the calling subscriber rings the code call without lifting his receiver, so that relay 5 is not energized and the call does not reach the exchange indicator 31, 30. He then lifts his receiver, energizing relays 1, 5, and when he hears the called subscriber take down his receiver he momentarily presses a key 11 to remove the short-circuit from the high-resistance winding 2 to permitenergization of the relay 1 of the called subscriber. If the exchange is automatic the subscribers' dial is connected as shown in Fig. 3. Non-operation of the relay 1 when the receiver is lifted serves as an indication that the party-line is busy.

Title: Respirator pumping apparatus
IPC: A61M16/00
Filed: 1959-07-01
Abstract: 806,907. Compressors. CONITECH Ltd. July 1, 1957 [July 17, 1956], No. 20746/57. Class 8(1). [Also in Groups VI & XXIV] An artificial respirator pump having a reciprocating piston and rod for cyclically varying the pressure in a respirator has motoroperated, actuating mechanism comprising a rotary driving shaft and a rotary driven shaft in eccentric parallel relation, a crank on the driving shaft which engages a radial slot of a crank on the driven shaft, so that the pump is operated more rapidly during the inhalation period than during the exhalation period of the breathing cycle, and a second crank rotated by the driven shaft and slidably engaging a slotted cross member fixed to the piston rod for reciprocating the piston. A piston 14 having a hollow rod 16 which is slidable on a fixed guide rod 17 is reciprocated in a cylinder 10 by an electric motor 34. The electric motor 34 is connected to the piston rod actuating mechanism through gearing 33 which rotates a driving brank arm 30 having a roller 30a which engages a slotted crank arm 27. The slotted crank arm 27 imparts rotation to a driven shaft 25 and a driven crank arm 24 having at its end a roller 24a which moves in a slot on a horizontal cross member 23 secured to the piston rod 16. The driving crank arm 30 is driven through a shaft 32 which is in eccentric parallel relationship to the driven shaft 25 so that rotation imparted to the slotted crank arm 27 is faster for one part of its cycle than the other. This variation in rotational speed is converted into correspondingly varied rectilinear motion of the piston by the sliding of the roller 24a of the driven crank arm 24 in the slot of the cross member 23 so that the inhalation inducing part of the stroke of the piston 14 is longer than the exhalation inducing part. A chest or belt type respirator is connected to the interior of the cylinder through a tube 36. The lower part of the cylinder 10 has a valve 44 for connection to atmosphere or to a point of use for example a mask. Relief valves 41, 42 are provided to prevent the pressure in the cylinder 10 exceeding predetermined negative and positive pressures respectively. Also, adjustable relief valves 37, 39 maintain the pressures in the cylinder within the ranges required for different types of respirator. Specifications 740,192 and 783,671 [both in Group VI] are referred to.

Adding and subtract. ing apparatus; multiplying and dividinq apparatus.-In key-set and independently electrically operated machines of the kind described in Specifications 5674/15, 5675/15, 203,236, and 203,351, and in which subtraction is effected by the addition of the complement, the key values are transferred to circuitclosing devices comprising groups of four contacts from which the digits can be made up for subsequent transmission to ball-actuated totalizing-counter mechanism. Three sets of circuit-closing devices are provided, one for the " item " and one for the " rate " in multiplication operations and one called " general " for operations involving addition and subtraction. The " item " and " rate " sets are associated with co-ordinating mechanism as described in Specification 208,737 for ascertaining the various partial products. The machine may be combined with any usual form of typewriter for printing any desired letterpress in addition to the numerals required. As shown, the current through the key-operated contacts passes by way of the leads h, Fig. 4, to one or other of a combination of the leads i, k, l as determined by selecting switches A - - D. The leads i, k, l are connected to corresponding " item, " " rate," and " general " circuit-closing devices, one of which sets is shown in Fig. 1 and comprises electromagnetically-operated switches d, spring-controlled slides a and two sets of contacts e, f arranged in groups of four, one for each denomination. The contacts e are normally open while the contacts f are normally closed. The particular group of contacts selected for receiving the key value depends on the carriage position, and that value is transmitted, when current is passed through the conductor e<1>, through leads e<2> to ball release mechanism for the counters, as described in Specification 208,737 referred to above. If the key value is to be subtracted the conductor e<3> is made alive to add the complement of the number set up. The arrangement of one of the totalizing-counters m - - p is shown in Fig. 2 with one denomination connected to the printing device r through normal and complementary contacts s, t. An additional counting disc q is provided to ensure that a single impulse will be given to the units denomination when subtracting a lesser number from a greater number.
